Traffic management of unicast service queues may be implemented through this collaborative manner.
  • Multicast service packets may be transmitted to the switching access unit of the egress PTN device through the switching network in a self-authorization manner.
  • the backpressure signal of the traffic control can be accurately transmitted to uplink queues when congestion occurs, such that packets can be buffered, the rate of packet transmission may be reduced, and the congestion can be alleviated.
